Any idea? what can I spray on them? Prefer no chemicals , Thanks much in advance.
Thanks, awesome post!Probably a caterpillar eating from the underside of the leaf. There are two non chemical organic sprays for caterpillars. The absolute best for only caterpillars is any product with the active ingredient of Bt (Bacillus thuringensis). I comes in a lot of brand names. The second is an all around pesticide with the active ingredient of Spinosad which also has a lot of different brand names. It will take care of any caterpillar or insect although on caterpillars it takes a little longer, about 2 days. Both of these products are completely harmless to people, pets and the environment and can be easily found online or at any real nursery.
